Which part of metallic bonding theory helps the most to explain why metals are able to conduct electricity?

Explanation:

The metallic bonding theory basically states  that valence electrons are free, delocalized, mobile, and not associated with any particular atom. It is pften regarded as a sea of electrons surrounding te atoms.

Metals are able to conduct electricity because of the free movement of the electrons (they are not bounded to a particular atom). Hence, electricity can be defined as the movement of electrons.
